years ago, VampireWicked mentioned doing a Persona spinoff series with a 20 something cast and hack and slash mechanics and a post on Yotube reminded me of that idea. It was about a protagonist going on their own than in a party.
From personal experience, I feel your college and post school years are lonelier than high school. So having an older protagonist go solo in a spinoff with hack and slash or beatemup mechanics felt interesting.
i also played Judgement recently and it also has the bones of that idea as well.
its food for thought for a potential indie game.
